simulator.py/RpcHandler() needs encode/decode to work these days

[kiml]

I needed to make the following change (Python 3.9) to make this code work.

@@ -90,13 +90,13 @@ class RpcHandler(SocketServer.BaseRequestHandler): """This function is called automatically by the SocketServer"""

self.request is the TCP socket connected to the client

     # read the incoming command

• request = self.request.recv(1024).strip()
• request = self.request.recv(1024).decode().strip()

  write to the queue waiting to be processed by the server

   INPUT_QUEUE.put(request)
   # wait for the server answer in the output queue
   response = OUTPUT_QUEUE.get(timeout=5.0)
   # send back the answer

• self.request.send(response)
• self.request.send(response.encode())

Hello, thanks for proposal. Can you please make a PR with this code. Is it still works in prior version of Python 3?
